GANG OR OULTIVATOR PLOW.

SPECIFICAA'JIIONl forming part of Letters Patent No. 634,358, datedOctober 3, 1899.

Application iiled November 4, 1898. Serial No. 695,465. (No model.)

lb all whom t may concern:

Be it known that l, JOHN THOMAS LUCAS, of lVasco, in the county ofSherman and State of Oregon, have invented a new and Improved Gang orCultivator Plow, of which the following is a full, clear, and exactdescription.

The principal object. of my invention is to improve upon theconstruction of gang or cultivator plows for which Letters Patentweregranted to me June 27, 1893, No. 500,405.

A further object of the invention is to provide a rear or guide wheelwhich will have but slight frictional engagement with the land and toprovide means forsimultaneously raising and lowering all of the sharesand for leveling the plow when necessary.

A further object of the invention is to provide an adjustable clevis anda simplemeans for operating the same and to provide the shares withdetachable landsides, whereby the shares will be prevented from slippinguponhilly or upon uneven ground.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding partsin all the figures.

Figure'l is a plan view of the improved plow. Fig. 2 is a side elevationof the same, and Fig. 3 is a detail perspective view of the shank forthe rear shaft and the share belonging to the shank.

The frame of the body of the implement consists, primarily, of two sidebeams A and B and two intermediate beams Gand CC The right-hand sidebeam Bis of zigzag shape, being bent to form a series of steps,(designated as b.) The intermediate beams C and C eX- tend beyond thefront portion of the two outer or side beams, while at the rear end ofthe plow the two side beams are brought together and the projectingforward ends ofthe intermediate beams C and C are given a downwardinclination, as shown in Fig. 2.

The side and intermediate beams are connected or braced together bycross-bars 10l and 1l, while a cross-bar 12 extends through the inclinedprojecting portions of the intermediate beams, and another cross-bar 13is provided for the said projecting portions of the intermediate beamsat their forward extremities.

Two parallel axles D and D' are provided for the frame of the plow, thesaid aXles being located near the front end of the plow and arejournaled in suitable bearings carried by the side frames A and B. Theforward axle D is provided with a crank-arm 14 at its righthand end,carrying a supporting-wheel 14:, while the rear axle D' is provided witha crankarm 15 at its left-hand end, which carries a supporting -wheel15, the two supportingwheels being practically in transverse alinement.

A hand-lever 16 is secured upon the straight portion of the forward axleD, near its crankarm, and the said hand-lever is provided with athumb-latch 17, adapted to engage with a suitable rack 18 on the frame,and a second hand-lever 19 is secured upon the straight portion of therear axle D', near its crankarm, the lever 19 being also provided with athumb-latch 20, adapted to engage with a rack 21, also secured to theframe. By manipulating the lever at the left of the frame and attachedto the rear axle the plowshares may be raised and lowered'and made totravel at any desired depth in the soil, while through the medium of thelever attached to the front axle the wheel that travels in the furrowmay be raised and lowered independently of the landside-wheel, so as tolevel the plow.

At the front end of the plow-frame a clevis 22 is located, the saidclevis being of angular construction. One member of the clevis isadapted to travel upon the front connectingrod 13, while the othermember is provided with a series of apertures 28, adapted to receive adraft device, and the clevis is llaterally shifted through the medium ofa handlever 24, fulcrumed, preferably, upon the connecting-rod 12, asshown in Figs. 1 and 2,

the forward-end of the leverhaving shifting engagement with the clevis.Then the clevis is constructed in the manner set forth, it may beshifted to vary draft to and from the land while the plow is in motion,and the loop connection 24:, which is provided between the clevis andthe lever, serves to prevent the lever binding on uneven ground, and theloop connected with the clevis-lever 24 is con- ICO nccted with theclevis through the medium l drivers seat 25, said seat being mounted yupon the rear portion of the frame.

The plowshares 2G are somewhat rectangular in general contou r, buttheir forward faces are coneaved and their rear faces convexed, and oneor more of the plows are provided with a landside 27, the landsidesbeing attached to the rear face of the share by means of lugs 2S, andwhere a landside connects with a share the outer face of the landside ismore or less convexed. The end of a landside farthest removed from ashare is connected with said share by a. brace 30, and the said bracesand likewise the landsides are detachably attached tothe shares, as theshares are reversible, both their upper edges 96 and lower edges 2&3"being cutting edges.

All of the shares with the exception of the rear share are connectedwith the zigzag bar B through the medium of shanks 2S), the upbottom ofthe sleeve 32, and upon the upper end ofthe shaft an arm 37 is secured,which usually extends forwardly and is prevented from moving toward theland by a pin 38, with which it engages, the pin being carried by theframe; but the arm is capable of moving to the right upon a suitableguide 39, provided for it. Thus it will be observed that the guide-wheelt will take care of itself when the plow is turned and need not be0perated by hand.

rlhe landsides 27, attached t0 the shares, prevent the said shares fromslipping upon hilly or upon uneven ground. The landsides are so shapedas to dispense with most of the friction common to other landsides,since the lower edges of the landsides are sharpened their full length,whereas the ordinary landsides are very wide at the bottom. The imiproved shares and landsides are especially adapted to plows supportedupon three wheels, as there is little pressure between the land and thebottom of the shares and their landsides, thus reducing the draft toabout onehalf less than that of other plows turning the same width.

per ends of the Shanks being,` provided with f heads that are bolted orotherwise secured to the steps l) of the said zigzag bar; but the shankof the hub said washers servingas caps and 5.

they form dust-protectors and likewise prevent the earth working intothe hub of the said guide-wheel. By constructing the rear sha-nk 3l asshown in Fig. 3 it is made compact and strong, and but one piece isnecessary where two pieces have heretofore been e m ployed.

The shaft 33 is provided with a collar 36 near its lower end, whichengages with the which l frame, of a plowshare having a shan k attachedl t l The landsides can be readily detached when it is necessary toreverse the shares or to remove them for sharpening.

Having* thus described my invention, I claim as new and desire to secureby Letters Patent l. ln a gang-plow, the combination with a to the shareand fixed to the frame, a sleeve carried rigidly by the shank, avertical shaft mounted in the sleeve, a rearguide-wheel supported by thevertical shaft at the lower portion thereof, an arm attached to thevertical shaft and extended forwardly, a guidel over which the armmoves, and a pin carried by the frame and serving to limit the movementof the arm in one direction.

2. A plow, having a share, a landside connected with the share andhaving a cutting or sharpened lower edge, and means for bracing thelandside against the share.
